It becomes allowable to the manager, kept on his guard by frequent 

 revisions, to determine for each stand not an operation prescribed a 

 long time ahead by a felling plan based entirely on age, but the opera- 

 tion actually adequate to its constitution, its cultural condition. This 

 is the technical advantage. But there is also an economic and com- 

 mercial advantage, in that the manager has permission to decide on an 

 excess cut, although for the moment prejudicial to the progress of in- 

 crement, and to make this cut at the most profitable time, taking advan- 

 tage of market conditions. 



The predetermined annual budget is only to determine the amount 

 of correction necessary. The law provides, however, that if the per- 

 missible cut is exceeded, the returns be placed in a special forest reserve 

 fund, from which to eke out the forest income in lean years, or make 

 extraordinary appropriations for improvement, etc. Reducing the cut 

 in unfavorable market conditions is, of course, also permissible.
